441.11 Quality Control Reports. Use Department Form TE-199 for the
Quality Control Report. Record all test results on the Quality Control Report.
Document all decisions regarding responses to test results on the Quality Control
Report (referring to the particular test), including reasons why a particular problem
may exist what action was taken to correct the problem (plant operation or testing),
and what communication with Department personnel took place. Submit one
Quality Control Report to the DET no later than specified. Retain copies of all
records documenting the quality control inspections and tests throughout the life of
the Contract and furnish them to the DET on request.
441.12 Mixture Deficiencies. Control all production processes to assure the
Engineer that the mixture delivered to the paving site is uniform in composition;
within the specification requirements and limits; conforms to the JMF: and that the
placed mixture is free of any defect (ex. segregation, tenderness, lack of mixture
and texture uniformity, raveling, flushing, rutting, holes, debris etc.) within the
Contractor’s control. Correct obvious pavement problems according to 401.15. If
any suspicion that other mixture composition or pavement problems exist, the
Monitoring Team will conduct an initial investigation through review of data and
sampling of the asphalt pavement. Should a Department investigation determine
that the Contractor’s QCP is not controlling the mixture in a manner to achieve
mixture quality as described above the Contractor quality control data may be
rejected. In that case the Department will conduct a thorough test investigation
based on samples from the roadway and use those test results in determining
disposition of the non specification material.
A mixture is not uniform in composition if multiple random non-specification
individual tests or any four consecutive non-specification moving accumulative
ranges exist. The mixture can be rejected, production can be stopped and/or a
redesign can be called for by the Department. The Laboratory will not approve
